Default BAD O2 sensor? How do you check?

So, if my car is running kind of poorly and fits some of the symptoms of a bad O2 sensor is there a way to check and see if that is the problem without just throwing down the cash to replace a part that might, or might not be bad?

My car has 104K on it. I bought it used about 60k ago and haven't put a new one on it.
